Figurel is a perspective view of a conventional Addressograph machine including a preference tab counter Patented Mar. 1, 1960 ICC Figure 5 is a diagrammatic wiring diagram of another set up of the attachment.

Figure 6 isa diagrammatic wiring diagram of still another set up of the attachment.

Referring now more specifically to the drawings, reference numeral 10 designates, in general, a conventional Addressograph machine having a plate or frame receiving magazine 12 secured thereto at the right rear of the machine, as viewed in Figure 1. The magazine 12 is supplied with a plurality of plates or frames 14 which may be provided with or without a plurality of tabs 17 (see Figure 3) positioned thereon in accordance with a predetermined system for the ascertainment of certain information according to the classification thereof.

The Addressograph ll} includes the conventional reciprocating carrier bars (not shown) for moving the frame 14 from the magazine to reciprocating cross-carrier bars of which one is designated at 16. By conventional means,

the cross-carrier bars 16 deliver the frames to another set of carrier bars (not shown) which move each of the frames 14 into printing position below an opening 18 formed in the topwall 29 of the machine 10. An inked ribbon 22 extends across the opening 18. The item to be addressed is placed over the opening 18.

A platten 24 is mounted for vertical and reciprocating movement in a housing 26 secured to the machine 10. Means are provided for moving the platten 24 toward the front of the Addresso-graph and then downwardly against the item to be printed. The platten is then moved rearwardly across the item to effect the printing impres- S1011.

Means (not shown) now convey the frame 14 to its proper file drawer 27.

in each cycle of operation, as the cross-carrier bars 16 move to the right, as viewed in Figure 3, the frame M is locked in motionless position by means of holding pawls (not shown). Now, as the carrier bars 16 are moved to the left, the frame 14 is removed and replaced with another.

The brief description above pertains to conventional Addressograph machines and does not relate to the present invention, per se, which is directed to an attachment therefor.

The attachment comprising the present invention in-, 'cludes two basic units, namely, an electric switch operating mechanism 23 and an electrical computing or indicator system 30 therefor.

The switching mechanism 23 comprises a pair of elongated substantially rectangular laterally spaced and parallel support bars 32, 34 having one of their respective ends fixedly secured to the chassis of t e Addressograph it The other ends thereof receive and support therebetween the opposite ends of a rod 36. The upper ends of the arms 33, as of a substantially U-shaped bracket 42 are mounted on the rod 36 intermediate its ends. The bight wall 44 of the bracket 42 is provided with a plurality of apertures 46 to serve a function to be described.

A plurality of normallyopen switches indicated at 48 are provided, each of the switches having their respective lxed component formed of an elongated substantially rectangular strip 50 of rigid conductive material on which is fixedly secured, adjacent an end thereof, a switch contact element 52. The strips 50 are apertured adjacent the other ends thereof, and these last mentioned ends terminate in longitudinally projecting lugs 54. The movable switch arm 56 is formed of a conductive resilient material and also has an elongated substantially rectangular configuration. A switch contact 58 is fixedly secured to one end of the switch arm 56, and an aperture is formed therein adjacent the other end thereof. As is seen in Figure 3 of the drawings, the other end of the switch arm 56 terminates in a longitudinally extending lug 59.

The fixed switch component 51 and the switch arm 56 are held in spaced, substantially parallel relation by means of the spacer block 60 formed of a dielectric material and having a substantially rectangular configuration. As is seen in Figure 3, the spacer block 60 is interposed between the other end of the fixed switch component 55 and the other end of the switch arm 56, and the three elements are fixedly secured to the bight 44 by a screw 62 which extends through one of the apertures 46 and is retained therein by a nut (not shown). The contacts 52 and 58 are, of course, disposed in confronting relation.

The movable switch arm 56 is engaged by one end of a cross-head 64 of a substantially T-shaped switch operating lever 66. The outer end of the stem portion 68' of the lever 66 terminates in an enlarged boss '70 having a central transversely extending aperture formed therein and extending therethrough. The rod 36 loosely extends through the aperture to rotatably mount the lever 66 thereon. Guide collars 72 are fixedly secured on the rod 36 by sets crews 74, the collars being disposed one on each side of the boss 70 and prohibit axial movement of the lever 66 relative thereto.

The arm 38, intermediate its ends, is provided with a laterally extending lever 76 having an opening 78 formed in the outer end thereof which is adapted to receive therein one end of a helicoidal spring 30 having the other end thereof fixedly anchored to the chassis of the machine It The spring 80 constantly biases the bracket 42 for movement in a clockwise direction, reference being made to Figure 3 of the drawings.

The other arm 40 of the bracket &2 is integrally formed with an elongated cam follower arm 82 which projects laterally therefrom. The cam follower arm terminates at its outer end in an integrally formed laterally and upwardly extending finger 84-.

An elongated substantially rectangular cam bar 86 is fixedly secured adjacent an end thereof by bolts 88 to the foot portion 90 of a substantially L-shaped bracket 92. The leg portion 94 of the bracket 92 has its outer end fixedly mounted on the carrier bar 16 adjacent one of its ends by the bolts 96.

The lower edge of the cam bar 86 is formed with an inverted substantially rectangular recess h? having sides 100, 102 which diverge away from the bight portion 1%.

The lower edge 87 of the cam bar 86 slidably engages the finger 84 during portions of the reciprocating movement of the carrier bar 16, and is adapted to enter the recess 98 and ride against the side 1% and bight portion 104 when the carrier bar 16 is moved to the right, reference being made to Figure 3 of the drawings. It is readily apparent from the foregoing description, that when the finger 84 enters the recess 98 the U-shaped bracket 32 and its associated elements will pivot in a clockwise direction.

A shaft 106 is mounted for rotation on the chassis of the machine and has a disc 108 fixedly secured thereon for rotation therewith. The disc 10% is eccentrically mounted on the shaft 106 at 110, and the disc 108 is rotatably received with a hollow cylindrical sleeve 112 having a radially extending outwardly projecting internally threaded hollow boss 114 integrally formed therewith.

One end of an elongated rod 116 is externally threaded for threaded engagement with the boss 114, and the other end thereof is mounted on one end of a pivot pin 118 having its other end fixedly secured to the outer end of a flange 120. The flange 120 is integrally formed with and projects laterally and upwardly from one end 122 of a bell crank lever 124. A pivot pin 126 pivotally connects the bell crank lever on the chassis of the machine 1%. As is seen in the drawings, the other end 128 of the bell crank lever 12% is provided with an elongated slot 130 which slidably and pivotally receives a pivot pin 132 mounted on one end of the elongated leg 134 of a sub stantially L-shaped lock bar 136. The foot portion 138 is formed with a laterally extending flange 140 which carries an offset keeper member 142. The keeper 142 is adapted to engage over a lock down lever 144 integrally formed with the cam arm 82 to hold the bracket 42 against pivotal movement in a clockwise direction when the carrier bar 16 is moving to the left, reference again being made to Figure 3 of the drawings. This prevents the other end of the cross-head 64 from obstructing the substitution of a new frame for the frame 14 shown in dotted lines in Figure 3 as the carrier bar 16 reciprocates.

A disc 146 is fixed for rotation with the shaft 106 and is eccentrically mounted thereon at 148. The eccen tric disc 146 is adapted to engage the switch arm 150 at timed intervals to close the timing switch 152 having a fixed contact 154.

A substantially L-shaped bracket 156 has the foot portion 158 thereof fixedly secured by bolt 16% to the carrier bar 16, and the leg portion 162 thereof is centrally apertured to receive the threaded bolt 164. The bolt is locked in adjusted position by lock nut 166. As the carrier bar 16 moves to the left (as Viewed in Figure 3) the head 168 of the bolt 164 engages against the switch arm 170 of a normally closed switch 1'72 to open a holding circuit to be described.

Referring now to Figures 3 and 4, one end of a wire 174 is connected with the fixed contact 176 of the holding switch 172 and the other end thereof is fixedly secured to a tine 178 of a connector plug 180. The switch arm 170 of the normally closed switch 172 is provided with a contact 182 and is connected by wire 184 with the fixed contact 154 of the timing switch 152, and the contact 154 connects with a second tine 186 of the plug through wire 188. The switch arm 15% having a switch contact 151 connects through wire 1% with the third tine 192 of the plug 180. The wires 1'74, 188 and 190 form a cable 193 which extends through an insulator bushing 1% mounted in the chassis of the machine 19.

The tines 178, 186 and 192 are releasably connected with sockets 195, 196 and 198, respectively, fixedly mounted on a side wall 200 of a substantially rectangular cabinet 292 having a front wall 204 and an upper wall 206.

The fixed contact 52 of the first of the switches 48 is connected through Wire 208 with one side 210 of a phone jack 212, and the contact 58 on the switch arm 56 connects with the detent member 214 through wire 216.

The second, third and fourth switches 48A, 48B and 48C all connect with their respective jacks 212A, 2128 and 212C in the same manner, that is, the contacts 52A, 52B and 52C connect through wires 208A, 2083 and 208C with one side 210A, 221MB and 210C of the phone jacks 212A, 212B and 212C, respectively. The contacts 58A, 58B and 58C are connected with the detent members 214A, 214B and 214C through wires 216A, 216B and 216C, respectively.

All of the jacks 212, 212A, 212B and 212C are mounted on a substantially rectangular base board 218 secured on the machine 10.

A plurality of electrically operated counters 229, 22t9A, 2203 and 2200 are fixedly mounted on the upper wall 296 of the cabinet 202 and are under the control of a plurality of single-pole double-throw switches 222, 222A, 2223 and 222C which are mounted in a horizontal row on the front wall 204 of the cabinet 202 adjacent the upper end thereof. Each of the switches 222, 222A,

222B and 222C are provided with movable switch arms 224, 224A, 224B and 224C which are adapted to normally engage the fixed switch contacts 226, 226A, 226B and 226C when in their Off position. The switch arms close against contacts 228, 228A, 228B and 228C when they are moved to their respective On positions. These switches are manually operated as well as the doublepole double-throw switches 238, 230A, 23013 and 230C mounted on the wall 204 of the cabinet 202. Each of these last mentioned switches include the pair of switch arms 232 and 234, 232A and 234A, 232B and 234B, and 232C and 234C, respectively, which normally in their-OE position engage the pairs of contacts 236 and 238, 236A and 238A, 236B and 238B, 236C and 238C, respectively. In their On position, these switch arms close against the pairs of contacts 240 and 242, 248A and 242A, 240B and 2423, 248C and 2420, respectively.

Also mounted in the cabinet 202 are a plurality of solenoid operated double-pole double-throw relay switches 244, 244A, 2448 and 244C. Each of these switches include pairs of switch arms 246 and 247, 246A and 247A, 246B and 247B, and 246C and 247C which in their respective Off position engage the pairs of contacts 248 and 250, 248A and 250A, 24813 and 250B, and 248C and 250C. In their On position, the last mentioned switches engage the pairs of contacts 252 and 254, 252A and 254A, 252B and 254B, 252C and 254C.

Each of the last named pairs of switch arms 246 and 247, 246A and 247A, 246B and 247B, and 146C and 247C are mounted on the armatures 256, 256A, 2563 and 256C of solenoids 258, 258A, 25813 and 258C.

One end of wires 260, 260A, 268B and 2600 are connected with the contacts 254, 254A, 254B and 254C, respectively, and their respective other ends are connected with one side of the solenoids 258- Wires 262, 262A, 2623 and 2620 have one of their respective ends connected with the wires 260, 268A, 26013 and 260C, and their respective other ends are connected to one side 264, 264A, 2643 and 264C of the phone plugs 266, 266A, 266B and 266C. The other sides of the solenoids connect through wires 268, 268A, 26813 and 268C with wire 270 which connects with one side of the secondary winding 272 of a transformer 274. The other side of the secondary winding connects through wire 276 with one end of the wires 278, 278A, 278B and 278C, and the other ends thereof connect with the switch arms 247, 247A, 247B and 247C, respectively. The other sides 280, 286A, 2803 and 280C of the plugs 266, 266A, 266B and 266C are connected by wires 282, 282A, 2823 and 282C with the wire 276. The Wires 262, 262A, 26213 and 262C together with the wires 282, 282A, 2828 and 282C forming the cables 284, 284A, 284B and 284C (see Figure 2).

One side of the counters 220, 220A, 22GB and 220C is connected by wires 286, 286A, 286B and 286C with the fixed switch contacts 238, 238A, 2383 and 233C. Wires 288; 288A, 2883 and 288C connect the other side of the counters 220 with one side of, the main line 290 (110 volts A.C.) through the wire 292. The other side 294 of the 110 volt line is connected withthe socket 195.

The socket 198 is connected through line 296 and wires 298, 298A, 29813 and 293C with the switch contacts 228, 228A, 228B and228C. Wires 300, 390A, 3003 and 360C connect the switch contacts 226, 226A, 2268 and 226C with the switch contacts 248, 248A, 2483 and 248C, respectively.

Wire 302 (shown in Figure4 of the drawings) is provided in the event one or more additional counters other than the four illustrated herein is to be employed. Other than this, the wire 302 serves no function in the present disclosure. On the other hand, wires 302A, 3023 and 302C serve to connect the switch arms 232A, 2323 and 232C with the switch arms 246, 246A and 246B.

Wires 304, 304A, 30413 and 304C connect the switch tacts 252, 252A, 252B and 252C, respectively. Wires 306, 306A, 306B and 306C connect the switch arms 224, 224A, 2243 and 224C with the fixed switch contacts 236, 236A, 236B and 236C, respectively. Wires 308, 308A, 308B and 308C connect the fixed switch contacts 240, 240A, 240B and 240C with the fixed switch contacts 242, 242A, 24213 and 242C. Wire 3110 connects the switch arm 246C with the wire 296, and Wire 312 connects one side of the primary winding 314 of the transformer 274 with one side of the main line 290. The other side of the primary winding is connected by wire 316 with the socket 196.

As is seen in Figures 4, 5 and 6, one side of the counters 220, 220A, 22813 and 220C are directly connected through wires 288, 288A, 288B, 28 8C, and wire 292 with one side of the conventional volt, 60 cycle, A.C. source 290. The completion of the circuit to any one thereof is dependent upon the positions of the switches 222, 222A, 222B, 2220, 230, 230A, 230B, 236C, 244, 244A, 2448, 244C, 48, 48A, 48B, 48C, 172 and, 152, which are connected between the other side of the counter 220 and the other side of the line 294. Thus, assuming that the plug 188 has been coupled with its sockets 195, 196 and 198, the primary coil 314 is energized through the circuit which reads from the line 294, socket 195, tine 178, wire 174, contact 176 of the normally closed switch 172, switch arm 170, wire 184, switch contact 154, wire 188, tine 186, socket 196 and Wire 316. As seen in Figure 4, the primary coil 314 remains energized until the switch 172 is opened, the opening thereof occurring as the carrier bar 16 terminates its movement to the left.

The other side of the counters 220, 229A, 220B and 228C are seen to be connected with the line 294 when .ever the switch arm of the switch 152 engages the fixed contact 154, assuming that the several control switches for each of the counters are in a given position. For example, in Figure 4, the counter 22tlC is actuated in the control circuit therefor which reads from the line 294, socket 195, tine 178, wire 174, contact 176, contact 182, switch arm 170, wire 184, switch contact 154, contact 151 on the switch arm 150, wire 190, tine 192, socket 198, wire 296, wire 310, switch arm 246C (this assumes the solenoid 258C as being energized), contact 252C, wire 304C, switch arm 234C, contact 238C and wire 286C to the other side of the counter 220C. Thus it is seen that the counters are actuated by the 110 volt line.

The solenoids, on the other hand, are energized under certain conditions by current which fiows from the secondary coil 272. It is to be understood that the transformer 274 is of the step down type, the voltage across the secondary coil 272 being 6 volts. .As has been explained above, one side of the secondary coil 272 connect through wires 270 and 268, 268A, 268B and 268C. Assuming for the purpose of illustration that all of the jacks 212, 212A, 212B and 212C have received all of their respective plugs 266, 266A, 266B and 266C, and assuming further that the switches 48, 48A, 48B and 48C are closed, the other side of the solenoids 258, 258A, 25813 and 258C connect with the other side or" the secondary through a circuit which reads as follows: wire 276, wires 282,, 282A, 282B, 282C, to the sides 280, 280A, 28013 and 280C of the plugs 266, 266A, 266B and 266C. From this last'named side, current travels through the sides 210, 210A, 210B and 210C of the jacks 212, 212A, 212B and 212C and through wires 208, 208A, 20813 and 208C to their respective connected switch contacts 52, 52A, 52B and 52C. The switches 48, 48A, 48B and 48C being closed, current flows through the swich arms 58, 58A, 58B and 58C to the jack detents 214, 214A, 214B and 214C to the other side 264, 264A, 264B and 264C of the plugs 266, 266A, 2663 and 266C. Wires 262,

arms 234, 234A, 234B and 234C with the switch con- 75 262A, 2623 and 262C connect the other ends of the plugs with the other side of the solenoids 258, 258A, 258B and 258C.

From the foregoing description it is clear that the solenoids 258, 258A, 258B and 258C will remain energized as long as the switch 172 is closed as well as the switches 48, 48A, 48B and 48C. It is pointed out, however, that a secondary holding circuit has been provided for the solenoids 258, 258A, 2588 and 258C which will maintain these solenoids in their energized condition subsequent to the opening of the switches 58, 58A, 58B and 58C. This secondary holding circuit is master controlled by the switch 172, and the holding circuit can only be destroyed upon the opening of the switch. The holding circuit is seen to comprise the wires 276 and 278, 278A, 278B and 278C which connect with the switch arms 247, 247A, 247B and 247C.

The solenoids having been originally energized, these last mentioned switch arms have moved into contact with the fixed switch contacts 254, 254A, 254B and 254C whereby current flows through the wires 260, 260A, 260B and 268C to one side of the solenoids 258, 258A, 258B and 258C. The other sides of the solenoids connect through wires 268, 268A, 26813 and 268C with the other side of the secondary winding 272 of the transformer 274 through the wire 270. The secondary winding 272 remains energized as long as the primary coil 314 receives current from the lines 298, 294. Thus the solenoids 258, 258A, 2583 and 258C, their holding circuits having been established, will only be deenergized when the carrier bar 16 strikes against the switch arm 170 of the switch 172 and breaks the contact between the contact 182 and the contact 176.

In the arrangement shown in Figure 4 of the drawings, the attachment has been set up in order to count the latest (that is the last tab to the right of the frame as illustrated in Figure 1 of the drawings) of any one of a series of four tabs which appear thereon. This, assuming that all four tabs 17 appear on the frame.

The switch 172 is closed, carrier bar 16 having released it upon the beginning of its travel to the right. The upward rotation of the bracket 42 will cause the cross-heads 64 to engage thereagainst depressing all four of the switch arms 56 to effect engagement of all of the contacts 58 thereon with the switch contacts 52 mounted on the strips 50 of the switches 48, 48A, 48B and 48C. At this moment all of the solenoids 258, 258A, 25813 and 258C are energized and effect a retraction of their respective armatures 244, 244A, 244B and 244C to move the switch arms 246, 246A, 246B and 246C and switch arms 247, 247A, 247B and 247C from engagement with the switch contacts 248, 248A, 248B, 248C and 250, 258A, 2585 and 256C to establish contact of the switch arms 246, 246A, 246B and 246C and 247, 247A, 247B and 247C with the fixed switch contacts 252, 252A, 2523 and 252C and 254, 254A, 254B and 254C, respectively.

As has been noted before, one side of all of the counters 228, 220A, 22813 and 220C are connected with one side of the line 298 through wires 292, 288, 288A, 2883 and 288C. The counter 2200 is now energized through the circuit which may be read from wire 286C, contact 2380, switch arm 234C, wire 304C, contact 252C, switch arm 246C and wire 310 to the wire 296. Wire 296 connects with the socket 198, the latter being in turn engaged by the tine 192 which is connected by wire 198 to the switch arm 150 of the switch 152. The contact 151 of the switch 152 is engaged with the contact 154 which is connected to the other side of the line 292 through the wire 184, switch arm 170, its contact 182, the switch contact 176, wire 174, tine 178 and socket 195. The counter 228 will not be energized inasmuch as the switch arm 246C is no longer in engagement with the switch contact 240C which connects the other side of the counter 220B with the other side 294 of the line.

If the counter 220 is to be actuated, the circuit from its other side must read wire 286B, contact 2383, switch arm 234B, wire 304B, contact 2528, switch arm 246B, wire 382 C, switch arm 232C, contact 236C, wire 306C, switch arm 224C, contact 2260, wire 300C, contact 248C and through the switch arm 246C (now moved into engagement with the contact 252C) and wire 310 and back to the wire 296 which is connected with the other side of the line as described above. However, since the switch arm 246C no longer engages with the contact 248C, counter 2208 can not be energized.

For the same reason, that is the shifting of the switch arm 246C from the contact 248C into engagement with the contact 252C, the counter 220A will not be actuated and the same applies in connection with the counter 220.

With the same arrangement as previously described, let it now be assumed that the tabs 17 appear at the first and third positions. Under these conditions, the switches 48 and 48B will close, energizing the solenoids 258 and 258A which will be maintained, thereafter, by means of the hereinbefore described holding circuits. Energization of the solenoid 258 will cause the switch arm 246 to establish contact with the switch contact 252 and the switch arm 247 will now engage against the fixed switch contact 254. In a similar manner the switch arm 2463 will be moved into contact with the switch contact 252B, and the switch arm 247B will make contact with the fixed switch contact 254B.

Under these circumstances only the counter 220B will register. This is established by an examination of the wiring of the other side of the two counters.

In connection with the counter 228B, the other thereof establishes electrical connection with the other side of the line 294 in the following circuit which reads wire 286B, switch contact 238B, switch arm 234B, wire 384B, switch contact 2523, switch arm 246B, wire 382C, switch arm 232C, contact 236C, Wire 3060, switch arm 224C, switch contact 226C, wire 300C, contact 248C, switch arm 246C and wires 310, 296 and back to the other side of the line, as previously described. Thus the counter 220B is seen to be actuated.

The counter 220 will not be actuated since the circuit to the other side thereof is broken when the switch arm 246B moved out of engagement with the contact 2488 upon energization of the solenoid 258B. This is seen by tracing the circuit which reads from the other side of the counter 220 through the wire 286, switch contact 238, switch arm 234, wire 304, contact 252, switch arm 246, wire 382A, switch arm 232A, switch contact 236A, wire 306A, switch arm 224A, switch contact 226A, wire 300A, switch contact 248A, switch arm 246A, wire 362B, switch arm 2328, contact 23613, wire 386B, switch arm 224B, switch contact 226B, wire 300B and switch contact 248B whose switch arm 246B has now moved away therefrom and engages against the contact 252B. Thus the circuit to the other side of the counter 220 is broken at this point.

Figure 5 illustrates the last of the two assumed set up examples which would have actuated the counter 220 (at the first station) had a tab 17 not been encountered by the cross-head 64B. Under these conditions, the switch arm 246B would have moved into engagement with the switch contact 248B, and the switch arm 2463 would have moved into engagement with the switch contact 250B since the coil 258B is not now energized. Thus, with the closing of the switch 48, the other side of the counter 220 is connected with the other side 294 of the line through wire 286, contact 238, switch arm 234, wire 304, switch contact 252, switch arm 246, wire 302A, switch arm 232A, switch contact 236A, wire 306A, switch arm 224A, contact 226A, wire 300A, switch contact 248A, switch arm 246A, wire 302B, switch arm 232B, switch contact 236B, wire 306B, switch arm 222B, switch contact 226B, wire 300C and through the contact 248B which has been actuated to close the switch arm 246B thereagainst.

The switch arm 246B connects through wire 302C with the switch arm 2320 which engages against the contact 236C, the latter being connected with the switch arm 2220 which is closed against the contact 2260. Con tact 2260 is connected with the contact 248C engaged by the switch arm 246C, the latter being connected to the other side of the line 294 through the wire 296.

Thus the counter 220 is actuated in the absence of a tab at the third position.

Figure 6 represents another set up for'the attachment. Under these conditions, the counter 220B will only be actuated when tabs 17 are present at the third and fourth stations. Absence of tabs at these points will interrupt the circuit to the counter 220 in the following manner. It is clear that with both of the solenoids 258B and 258C energized, the switch arms 246B and 246C have moved into engagement with the switch contacts 252B and 2520. At the same time, the switch arms 247B and 2470 have moved into engagement with the switch contacts 254B and 254C. Thus the other side of the counter 220B is connected with the other side of the line through wire 286B, switch contact 2383, switch arm 234B, wire 304B, contact 252B, switch arm 246B, wire 302C, switch arm 232C, contact 236C, wire 308C, switch arm 234C, contact 252C, switch arm 246C, wire 310 and wire 296. Obviously, if either of the two switch arms 24613 or 2460 had notengaged the contacts 252B and 252C, the counter 2208 would not have been actuated.

In addition to this tabulation, the counters 220 and 220A will count only the latest of the other two remaining tabs. Under this assumed set up, the counter 22% will be actuated if a tab is encountered by the crosshead 64, while the dotted line circuits indicate the actuation of the counter 220A which would be operated if the cross-head 64A had encountered a tab 17 whether or not the cross-head 64 alsoengaged a tab 17.

With a tab present at the first station, the other side of the counter 220 is connected with the other side of the line through wire 286, contact 238, switch arm 234, wire 304, contact 252, switchrarm 246, wire 302A, switch arm 232A, contact 236A, wire 306A, switch arm 224A, contact 226A, wire 380A, switch contact 248A, switch arm 246A, wire 302B, switcharm 232B, switch contact 236B, wire 306B, switch arm 224B, contact 228B and wire 296.

Now if tabs 17 were found present at the first and second stations, switch arm 246A would have moved from engagement with the switch contact 248A thereby breaking the circuit to the other side of the counter 228. At the same time, solenoid 258A actuates the armature 256A to establish contact between the switch arm 246A and the switch contact 252A. This completes the circuit to the counter 220Ain the manner described above, the counter 220A designating the presence of a tab at the second station regardless of the fact that a tab may also be present at the first station.

It should be noted that these last series of controlsare established by moving the switch arm 224B from engagement with switch contact 226B and establishing the engagement thereof with the contact 228B.

It is to be understood that the cross-heads 64. engage tabs 17 corresponding thereto as the carrier bar 16 moves to the right allowing the finger 84 to ride upward- 'ly into the recess 98 under the influence of the spring 80. At this time the eccentrically mounted disc 108 has rotated in the sleeve 112 in such a manner as to actuate the bell crank lever 124 in such a manner as to cause the keeper 142 to withdraw from engagement with the lever 144. The bracket 42 is now free to pivot upward to close anyone of the selective switches 48, which will energize any or all of the solenoids 258, 258A, 2583 and 2580. It is also understood that as the carrier bar 16 begins its movement to the right, the switch 172 is released, thereby closing the circuit to the selective switches 48, and to the holding circuits. Now as the carrier bar 16 begins its movement to theleft, it picks up a new frame 14 for positioning over the cross-heads 64, and simultaneously carries away therefrom the last sensed frame. However, prior to the positioning of the new frame over the cross-heads 64, the finger 84 rides out of the recess 98 and engages the lower ledge of the cam bar 86. This causes the bracket 42 to pivot downwardly and places the lever 144 below the keeper 142. Simultaneously, the keeper 142 is actuated by the bell crank lever 124 to effect engagement with the lever 144 to lock the bracket 42 in its lower position.

At some time between the movement of the carrier bar 16 from the left to the right, the disc 46 closes the switch 52, thereby energizing the counters which were selected by switches 48 and this selection being held by means of a holding circuit. As the carrier bar 16 approaches the end of its movement to the left, the switch 172 is moved to its open position and thereby breaking the circuit to the holding circuits.

It should also be noted that the camtimer switch 152 has nothing to do with the holding circuit of the solenoids 258, 258A, 2583 and 258C, but only makes a contact to complete the circuit to counters for the proper time.
